Cleaning/adjusting while intake is off...

[mateo1279]

Finally have all the parts to complete my intake/carb/valve cover swap... should be doin' it on the 8th-9th.

While I have the valve covers and intake off are there any adjusments, tuning, or cleaning I should do or be prepared to do? I am mainly thinking in terms of the vavle train, but I might be over looking something....

Motor: Bone stock 283 in my 62 chevy.
Stock intake manifold - Holley duel plane
Stock 2bbl carb - Holley 4160 4bbl
Stock covers - new covers with breather/pcv provisions

Thanks All!
